Abstract

Abstract: In this paper, the effect of a low carbon steel on microstructural and mechanical properties during quenching in CNT Nanofluids has been investigated. CNT nanofluids have been prepared and used as quenchants to study the effect of CNT dispersion, its concentrations and agitation on the heat transfer rate during quenching. However, the microstructure and mechanical properties of the steel that is being quenched in CNT Nanofluids were not yet analyzed. Hence in this research, a low carbon steel of grade AISI 1010 was chosen and quench probes of diameter 20 mm and length 50 mm were machined. They were then quenched in three different quench mediums namely distilled water (D.I), water based CNT nanofluids with and without surfactant. After quenching, the microstructure, surface roughness and hardness of the quenched probes were investigated and found high surface roughness on probes quenched in CNT nanfluids. Also, probes quenched in CNT nanofulid prepared with surfactant had higher hardness and the microstructure of probes quenched in different quenching mediums varied.
